EYEGLASS-CLEANER.

To all whom it may concern:

Be it known that I, CHARLES LnI-IMANN, a citizen of the United States of America, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Eyeglass-Cleaners, of which the .following is a specification.

This invention has reference to improvements in eye-glass cleaners and has for its special purpose to produce cleaners for eyeglasses which remove dust, moisture, dirt and the like from the glasses quickly without injuring them in the course of time.

It is the object of the present invention to produce an eye-glass cleaner for pocket use in which the effective element is chamois skin, the active surfaces of which however are protected. Both sides of a lens are cleaned at once in a thorough manner.

All parts of the novel eye-glass cleaner are interchangeable and care has been taken to produce a neat and desirable article all as will be fully described hereinafter with reference to'the accompanying drawing in which:

Figure 1 represents in side elevation an eye-glass cleaner which embodies in desirable form the present improvements. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a vertical section on line 3-3 of Fig. 1. Fig. 4 is a longitudinal section on line 1-4 of Fig. 2. Fig. 5 is a rear view of a detail part of the device and Fig. 6 represents the method of using the eye-glass cleaner.

Similar characters of reference denote like parts in all the figures.

The novel eye-glass cleaner consists essentially of two rotatable pads 0r cushions mounted in a suitable frame which serves as a handle. I

In the drawing a, a represent each an outside metal disk preferably of circular shape. Each disk has centrally a circular opening in which a short tube is secured These short tubes 6, b are threaded on the inside. An interior metal disk 0 has centrally a short metal rod (Z threaded on the outside which fits the interior thread of the short tube 1) of the outer disk at. A like interior metal disk 0 with a like short metal tube (Z centrally thereon and threaded on the outside fits the interior thread of the short metal tube b of the outer disk a The inner disk 0 has on its Specification of Letters Patent.

Serial No. 616,295.

inner surface a layer of felt 6 over which a layer of chamois skin f is tightly drawn and secured on the other side of the disk from where the metal rod protrudes by stitching as shown in Fig. 5. A like layer of felt c is provided on the inner surface of the disk 0 and a like layer of chamois skin 7 is tightly drawn over this felt and secured in a like manner by stitching on the other side of said disk 0 The threaded metal rods (Z, (Z have each centrally a short boring for a purpose to be explained farther down. The frame above referred to consists of two congruent members g, 9 made of elastic metal strips. These are secured together with their outer ends by a short bolt or rivet h. At about the middle each member is bent under a right angle twice so that the inner portions 9 are parallel each to its outer portion. The frame members carry each on the inner end portion a small pin extending inwardly which pins are designated by the reference characters 6, i, see Fig. 2. These pins fit into the short borings of the rods (Z, (Z o the inner disks 0, 0

In order to assemble the device each outer disk is screwed onto a threaded metal rod of an inner disk, then the two disks are pressed together with the chamois surfaces in contact with each other. Now the metal frame is pushed onto the outer disks and the two short pins 2', z" are placed into the short borings of the metal rods on the inner disk.

When the device is to be used one lens of the eye-glasses is placed between the chamois surfaces and the two padded disks are rotated on the short pins of the frame whereby the lens is thoroughly and quickly cleaned without any danger of scratching as the padded disks cover one another avoiding thus the collection of dust and grit. In Fig. 6 of the drawing a lens is shown partly inserted between the two padded disks.

From the above description it is clear that all the parts of the novel device are interchangeable and the chamois skin portions may also be replaced if desired.

I claim as my invention:

1. A rotatable eye-glass cleaner comprising two disks each with elastic chamois covering on the inside, an exteriorly threaded rod centrally on each disk, an outer disk with short tubular central portion interior-1y threaded and adapted to engage the thread of the short rod of the inner disk, and means chamois, an exteriorly threaded rod cen-' trally on each disk with short central boring, an outer disk with short tubular central portion interiorly threaded and adapted to engage the thread of the short rod of the inner disk and a frame composed of two members having each a short pin in the inner end portion fitting into the short bore ings of the metal rods of the inner disks.

3. A rotatable eye-glass cleaner comprising two circular disks padded each on the inside and having a surface covering of chamois, an exteriorly threaded rod centrally on each disk with short central boring, an outer disk with short tubular central portion interiorly threaded and adapted to engage the thread of the short rod of the inner disk, and a frame composed of two members made of elastic metal strips having each'a short pin in its inner end portion fitting into the short borings of the metal rods of the inner disk each member being bent inwardly beyond the padded disks and connected with their outer ends.

4. In a rotatable eye-glass cleaner two rotatable disks having each on the inside an elastic chamois covering, an exteriorly threaded rod centrally on each disk with short central bo-rings, an outer disk with short tubular central portion interiorly threaded and adapted to engage the thread of the short rod of the inner disk, and means in connection with the short borings of the metal rods of the inner disks for sup-. porting said disks in a contacting position.

Signed at New York, N. Y., this 22d day of March, 1911.
